It could be cool to be able to customize the character.

@ is quite common. What other char do you have in mind?

[bmspereira-07]

Something like this maybe https://tiptap.dev/docs/editor/extensions/nodes/mention#suggestions.

It would be cool to have an API just like select does.

->getMentionSearchResultsUsing(
    fn (string $search): array => User::query()
            ->where('name', 'like', "%{$search}%")
            ->limit(50)
            ->pluck('name', 'id')
            ->all()
)

This would allow dynamic searching and not have to return all the mentionables from the database.

Hey there! I updated the pull request with some changes, now you can add multiple symbols with the respective items and a global function to limit the number of results it shows when your using the mentions.

It would be great to get mentions back in the rich editor like it was with awcodes/filament-tiptap-editor. I'm rooting for this PR!

[danharrin]

I would accept this if it allowed a server request to load mention search results. Otherwise, I think the scope is quite limited as loading every user into JS in a large app would be slow.
